Outer hanging-wall plate connecting piece

Abstract

The invention relates to an outer hanging-wall plate connecting piece which is characterized by comprising a surface-layer steel plate, an inner-layer steel plate, a bolt rod and a nut, wherein the surface-layer steel plate is connected with the inner-layer steel plate by the bolt rod, one end of the bolt rod extends out of the inner-layer steel plate and is fixed on the inner-layer steel plate by the nut, and the other end of the bolt rod extends out of the surface-layer steel plate and is used for connecting an outer hanging-wall plate and a frame girder or a frame post. The outer hanging-wall plate connecting piece is used for connecting the outer hanging-wall plate with the main-structure frame girder and the frame post, not only ensures the safety and the reliability of the wall plate, but also has good anti-earthquake performance, is convenient to construct and install and has the advantages of construction cost reduction. A pulling test of an embedded piece indicates that the pulling force of the novel embedded piece can reach 120kN; and under the simulated actions of horizontal wind load and earthquakes of a high building of 50 meters, the connection of the outer hanging-wall plate with the main-structure frame girder and the frame post is not destroyed, therefore the same anti-earthquake performance is realized for a non main structure and a main structure, an enclosure structure can be guaranteed not to be destroyed before the main structure is destroyed under the action of the earthquakes, flexible connection of the enclosure structure is realized and the ductility and the integrity of a wall body as well as the integral anti-earthquake performance of buildings are enhanced.

Description

Technical field: [0001] The invention belongs to the technical field of civil engineering, in particular to an external wall board connector. Background technique: [0002] With the advancement of urbanization in my country, building energy consumption will eventually surpass industry and transportation to rank first in energy consumption. Building energy conservation will become one of the most effective measures to improve social energy use efficiency and alleviate energy shortages. The energy-saving technology of building wall insulation will become an important breakthrough in building energy conservation. In 2005, the state promulgated the Design Standard for Energy Conservation of Residential Buildings in Severely Cold and Cold Areas (JGJ26-2005), which specified the current goal of building energy conservation and demonstrated the importance of building energy conservation. At this stage, building energy conservation must reach the total energy saving 65% is even mor...

In 2005, the state promulgated the Design Standard for Energy Conservation of Residential Buildings in Severely Cold and Cold Areas (JGJ26-2005), which specified the current goal of building energy conservation and demonstrated the importance of building energy conservation. At this stage, building energy conservation must reach the total energy saving 65% of the more difficult tasks

Using traditional connectors, there are two problems: 1. The anchorage length of the connectors is relatively large, which needs to be embedded more in the structural layer, so it is often necessary to increase the thickness of the wallboard or increase the thickness of the wallboard at the embedded part to form a corbel. Increasing the thickness of the entire wallboard will greatly increase the cost of the wallboard. If the thickness is only increased at the embedded part to form a corbel, in addition to increasing the manufacturing and processing costs, it will also cause trouble for interior decoration and use; 2. Due to the long anchor bar , the structural layer is thin, so that the anchor bar of the traditional embedded parts bends upwards more, and the construction quality is difficult to guarantee; 3. The traditional embedded parts are welded to the surface of the angle steel, and the welded joints often crack after a certain number of years of use, which increases the secondary Maintenance costs, or potential safety hazards
